Protesters were previously told they could gather without a permit, as long as they stayed within the confines of Dewey Square.

“This is a brand new area that the Greenway put a lot of resources into and they filled it up with all kinds of tables and tents and were making it a place to camp out. It’s not what it’s intent is,” Superintendent-in-chief Daniel Linskey told WBZ NewsRadio 1030.

“This is the first day the communication broke down between the protesters and the police,” Police Commissioner Ed Davis told WBZ NewsRadio 1030.

“The people who we had been speaking to for ten days make it clear that there were a group of anarchists that were uncontrollable that had taken charge. So, when they decide they’re going to shut down large sections of the city or go into areas that we’ve said are off-limits, we have to deal with them accordingly.”

Anderson said the relationship with police started well but “apparently we crossed a line in the sand that Boston Police had put down and our relationship did change last night. Their response was deplorable. It was violent. People were injured. People were denied medication. Hundreds of people were arrested and our relationship has changed. We’re not really sure where it’s going to go.”

In a statement Tuesday, Boston Police said:

“Although our officers faced active resistance from protesters including being spit on, our officers maintained a respectful, professional and proportional posture. If any individual experienced a concern about their interaction with an officer that individual is encourage to come forward and report that information to the department. At this time, we have not received any such complaints.”
